n8n & Workflow Automation

n8n orchestrates credentials and executes actions across your entire stack - that makes security non-negotiable. This guide walks through a defense-in-depth architecture to mitigate CVE-2026-21858 and CVE-2026-25049 in production deployments.

Fragile API bridges between Claude and n8n break the moment requirements change. MCP gives your AI agents semantic understanding of your entire workflow library - this guide shows you how to build that bridge properly.

Running LLMs in n8n without a cost strategy is how you wake up to a five-figure cloud bill. This guide covers a layered approach - from upstream filtering to intelligent model routing - that can reduce your AI spend by 5x to 50x.

When n8n AI agents forget everything between sessions, you've hit the production memory wall. This guide walks you through a three-tier Redis, PostgreSQL, and vector embedding architecture that makes your agents remember - and scale.

Multi-agent n8n systems fail in ways single workflows never do - lost messages, context drift, infinite loops. This guide gives you a structured methodology to diagnose and fix production issues before they spiral.

Move past simple automations to build robust, error-handling N8N workflows that can handle real-world edge cases and failures.
